|Approaches for teaching planetology - Greeley, R|
The primary objective of the short course in lunar geology is to provide information and ideas for instructors so that aspects of planetology can be introduced or expanded in their earth science curriculum. Although the ways that this is accomplished are probably as varied as the number of participants, some suggestions for incorporating planetology into earth science programs are offered. Three general possibilities are: (1) Supplemental instruction in existing courses; (2) introduction of spec...

|Intersubband Transitions in InAs/AlSb Quantum Wells - Li, J.|
We have studied intersubband transitions in InAs/AlSb quantum wells experimentally and theoretically. Experimentally, we performed polarization-resolved infrared absorption spectroscopy to measure intersubband absorption peak frequencies and linewidths as functions of temperature (from 4 K to room temperature) and quantum well width (from a few nm to 10 nm). To understand experimental results, we performed a self-consistent 8-band k-p band-structure calculation including spatial charge separatio...

|LinkFinder: An expert system that constructs phylogenic trees - Inglehart, James|
An expert system has been developed using the C Language Integrated Production System (CLIPS) that automates the process of constructing DNA sequence based phylogenies (trees or lineages) that indicate evolutionary relationships. LinkFinder takes as input homologous DNA sequences from distinct individual organisms. It measures variations between the sequences, selects appropriate proportionality constants, and estimates the time that has passed since each pair of organisms diverged from a common...

|BBC Research and Development Report Number 1960-21|
R&D Report 1960-21 : Secondary flare in optical lenses. K. Hacking The image formed by a lens is often reduced in contrast by extraneous light spread extensively over the image plane as a result of specular interfacial reflections within the lens and scattering by surface irregularities. A method of measuring the magnitude factor of the lens and the flare component due to specular reflections is discussed...
